In statistical wireless signal processing, extraction
of unobserved signals from observed mixtures can be
achieved using Blind Source Separation (BSS) algorithms.
Orthogonal Frequency Division Multiplexing (OFDM) and
Direct Sequence-Code Division Multiple Access
(DS-CDMA) can be pronounced as the well established
predominant air interface communication techniques. Consequences
of an effort taken and counteractive solutions to
diminish the undesirable influences encountered within the
wireless air interface of those techniques with aid of BSS
schemes are disclosed. Filter coefficients for the receiver are
ascertained with the support of a set of energy functions and
the iterative fixed point rule. Time correlation properties of
the channel are taken advantage for BSS. Performance of
the algorithm are evaluated using OFDM and DS-CDMA
models under slow fading channel conditions with a receiver
containing Equal Gain Combining. The importance is that,
this scheme can be promoted as a low computationally complex
mechanism.

Do the benefits of polyandry scale with outbreeding?
Burdfield-Steel, Emily; Auty, Sam; Shuker, David M. (Oxford University Press; International Society for Behavioral Ecology, 2015)There have been many potential explanations put forward as to why polyandry often persists despite the multiple costs it can inflict on females. One such explanation is avoidance of costs associated with mating with ... -
